Drupal\Core\Entity\Query\QueryException: Entity queries must explicitly set whether the query should be access checked or not.

Changed the loadDefault function inside MarketplaceStorage.php to:

  public function loadDefault(AccountInterface $user = NULL) {
    $default = NULL;
    if ($uid = $this->getCurrentUserId($user)) {
        $config = $this->configFactory->get('commerce_marketplace.settings');
        $uuid = $config->get("owners.{$uid}.default_store");
        $query = \Drupal::entityTypeManager()->getStorage('commerce_store')->getQuery();
        $ids = $query->condition('uid', $uid)->accessCheck(TRUE)->execute();
    }
    elseif ($defaultStore = parent::loadDefault()) {
        $uuid = $defaultStore->uuid();
        $query = \Drupal::entityTypeManager()->getStorage('commerce_store')->getQuery();
        $ids = $query->accessCheck(TRUE)->execute();
    }

    if (!empty($ids)) {
        $stores = $this->loadMultiple($ids);
        if ($uuid) {
            foreach ($stores as $store) {
                if ($store->uuid() == $uuid) {
                    $default = $store;
                    break;
                }
            }
        }
        else {
            $default = end($stores);
        }
    }
    else {
        $stores = $this->loadMultiple();
    }

    if (!$default && isset($store)) {
        // This is the case when previously assigned default store was
        // deleted, so we need to return at least the last found store.
        $default = $store;
        $default->enforceIsNew();
        if (count($stores) > 1) {
            $this->messenger()->addWarning($this->t('No one default store is assigned yet. Note that it is recommended to have one explicitly assigned otherwise the last found store will be dimmed as the default. This may lead to unexpected behaviour.'), FALSE);
        }
    }
    elseif (!$default && $stores) {
        // As a last resort let's return the first store in the list.
        $default = reset($stores);
    }

    return $default;
}

On /store/add, the same error appear pointing to loadMultiple
#2 /app/web/modules/contrib/commerce_marketplace/src/MarketplaceStorage.php(70): Drupal\commerce_marketplace\MarketplaceStorage->loadMultiple()

I've changed the loadMultiple function, in order to work, to :

public function loadMultiple(array $ids = NULL, AccountInterface $user = NULL) {
    $stores = [];

    // If $ids are provided, load the entities directly.
    if ($ids) {
        $stores = parent::loadMultiple($ids);
    } else {
        // If $ids are not provided, build the entity query.
        $query = \Drupal::entityTypeManager()->getStorage('commerce_store')->getQuery();

        // Add condition based on the user, if provided.
        if ($user) {
            $query->condition('uid', $user->id());
        }

        // Execute the query and load the entities.
        $ids = $query->accessCheck(TRUE)->execute();
        $stores = parent::loadMultiple($ids);
    }

    return $stores;
}

Hii @farhadhf and all maintainers I have created MR for the above issue, Please review this
Thanks !!

Thank you @Harpreet_singh_saluja , I have another place where this error also happens:

on /admin/commerce/config/store

Operations: #0 /app/web/core/lib/Drupal/Core/Entity/Query/Sql/Query.php(80): Drupal\Core\Entity\Query\Sql\Query->prepare()
#1 /app/web/modules/contrib/commerce_marketplace/src/Plugin/Field/FieldFormatter/MarketplaceTypeLabelFormatter.php(94): Drupal\Core\Entity\Query\Sql\Query->execute()

I've replaced this (94) line:
$used = count($this->storage->getQuery()->condition('uid', $uid)->condition('type', $store_type)->execute());

To this:

$query = $this->storage->getQuery();
$query->condition('uid', $uid);
$query->condition('type', $store_type);
// Explicitly set whether the query should be access checked
$query->accessCheck(FALSE); // or TRUE if access checking is needed
$used = count($query->execute());

created a child issue for that and created merge request there too. @alexberendei thanks for point it
